Weighted Chins programming

I have run a LP with weighted chins up to 45x5x3 and this has now stalled out.
I am just about to start the Bridge (finishing up SSNLP having reset squats, lighter day etc. general non progress) and would really like to continue training the weighted chin.

Should I just do them on the GPP days - on one go for higher weight and lower reps and then on the other GPP day go for accumulated volume (as per the program)?

Or, would it be better/possible to add in or substitute weighted chins on of the other training days and follow similar sets/reps recommendations as say the bench press?

Basically I really like weighted chins and want to make sure I can keep them going without screwing up the program!

Many thanks for your time and the vast amounts of useful content you guys put out!

Your first idea is reasonable.

We would not recommend replacing something in the program with weighted chins.
