Patterns to change at sync point regardless of where they are in their pattern

[theotteryears]

I use Nerdseq mainly to control a lot of other sequencers, sending clocks and resets out to them. 

I really need the ability for the patterns to ignore where they are in their own patterns and all change together at the sync point when asked to. Is this possible? am I missing something?

I have a pattern with 16 steps, and a pattern with 15 steps. When I select a new row I would like them both to start from row 0 on the sync point. at present, the patterns finish their patterns entirely before changing.

Thank you in advance.
