Can I quantize Clips Start and End time in SONAR X1C??????

Hi I've starting to use Matrix view and I think will use it all the time.
 
Here is the process.
 
I performed and recorded some clips via Matrix view on Track view
 
and they were all out of time.
 
But here is the problem. I can't quantize Audio Clips perfectly!!!!!
 
Of course I can quantize Clip's Start time via Quantize option. However there is no Clip's End time quantize function!!
 
Besides sometimes even quantize Clip's Start time option doesn't work well either!
 
I need to quantize both start and end time of clips!!!!
 
Does Anyone know how to do this?
 
Any suggestion would be appreciate ㅠㅠ
