Howdy, super smart people!

I could not find if this had already been answered, so I hope this isn’t a repeat.

Problem:  I have my customers bucketed into tenure groups (e.g., 1-6 months, 7-12 months, 13-24 months,...) and it works great.  However, I now find the need to create a few buckets that overlap the current ones (e.g. 10-14 months) to capture their renewal experience, but i also don’t want to lose the 7-12 months and 13-24 month buckets.  Does anyone know how to do this?  I know I could create a second bucketed groups, but I am hoping there’s a way to simply allow these to overlap in the current bucket.

Thanks!
