Can you buy a step sequencer for Sonar Home ?

no, its not  separate plug in.
piano roll is the key.
its used in almost every daw out there, even the cheap ones.

this is how easy it is to write drums with the piano roll.

In the MIDI track pane, select New Drum Map>Session Drummer 2. That should bring up the SD 2 names.
It worked for me.

The octave below the Session Drummer instruments plays the MIDI patterns loaded in Session Drummer. The General MIDI Drum names should line up with the Session Drummer instruments however not all the instruments will sound. Whether a note sounds or not depends on the kit loaded in Session Drummer. You could try using the Session Drummer drum map, some find it easier to work with drums in the PRV using a drum map. There should be a Session Drummer drum map already defined so all you have to do is load it up.

How do you import drum map midi into the PRV?

Bansaw, you already have the SD2 drum map in place, as Greg suggested. Your screen shot shows that.
The snap to grid setting just draws your notes to the nearest increment. As you have it set in post #7, your notes will be drawn to the nearest eighth note. It does not give you "placeholders".

The sequencer you have shown just happens to have 16 slots showing.
You really have a lot of flexibility with the PRV in SHS6. You don't need placeholders, and you are not limited to the available slots in the sequencer.
The grid in the PRV gives you your reference points. You can set the grid resolution to any note value you would like to use. In post #7, you have it set to quarter notes, so your project is probably set to 4/4 time.

You can do a sequencer-like procedure in the PRV. I actually prefer doing it this way, because I have absolute control, instead of relying on the step sequencer to interpret what I mean to do.




In this view, I have the Session Drummer 2 map selected as the output of my MIDI track, so the PRV shows the correct drum names.
In the track view, I have set loop points so that measure 1 loops continuously.
In the PRV, I can add, delete, or move notes as measure 1 loops. Snap to grid is set to Real Time-0.00 so that notes can be placed precisely where I want them. Snap to grid tends to even them out too much, and make it sound mechanical. I have essentially turned it off.
Once I have the pattern the way I want it, I can go to the track view, select the measure(s), and convert them to a groove clip. Instant loops.
You can put the loop points anywhere you want, so you can dial in any specific part of your MIDI track.
Play with this a bit. Once you get a feel for it, I think you'll like it.

Glad to help. It looks like you've got the idea.
Don't forget about velocity. That goes a long way toward breathing life into your drum tracks.
