Quantize Length Help! Please!

Hi!

I apologize if this was posted before. I did do a search and found nothing on this. For the life of me I cannot get Quantize Length to work on Audio

Essentially what I am looking to do
Record a Guitar Part , Double Click Editor. Adjust threshold to create Slices

Press “Q” to Quantize to Beat
However once I do that I want to Quantize the Length

So say I have a Measure of all 8th Notes. I get every note Sliced and lined up. Some Notes are Longer/Shorter and I now want to Quantize the Length to 8th notes.

Sorry if I am being too descriptive. I’m trying to speed up my work flow

Please help
