DIYBMS software rules need

i have installed the V4 with 14 modules V4.4.
i missing some important rules and funktions.
balancing:
there is no field where i can change the STOP for balancing function. Example: Stop at differenz of 50mV
there is no field where i can configure a error rule for the cell differenz in mV.
there is no field where i can configure a error rule for the cell temperature high low and differenz.
i need the balancing function on 3 different situations:
-balancing in charging ,( data are from the shunt )
-blancing in dischraging
-balancing only at store
all the 3 functions must working on V4 and newer one

is anyone there, if can write the software for the functions. i needed it for my powerwalls with NMC cells.
i think the softwareupgrade help a lot of people
thanks
