Sure you can clip the front of the track to move it to the left.
MC 5 should have a Split tool, looks like a pair of scissors. Click that, set your Snap-to resolution so you can split the track just before your perfect second guitar track begins. Click at that point and the track should be split.
Right-click the part at the beginning, select Edit>Delete, and it will be gone, allowing you to slide the remaining clip to the left.
You can also right-click on the clip where you want to split it and select Split.
Focusrite makes good stuff. I love my Focusrite Saffire.
