MT4 PAMM Predefined Volume

Hi there

I´m using a PAMM module for MT4 to trade multiple accounts, I was wondering if there is a plugin or a way to save the predefined volume for each account as every time I change the symbol it all goes back to zero, since there are many accounts this has become impossible to manage. I have used “on equity ratio”, but the PMAM rounds the number and sends a larger order, also not very precise so not an option anymore.

Many thanks!
