Anyone know a way to add more parameters to the optimization tab?

For example better bollinger bands only shows Period and Multiplier to select for optimization,
but the indicator also has more parameters.
like smoothing method, base price, signal shift, indicator symbol, longer time frame etc which I cannot choose to optimize.

Also, when there are multiple entry or exit indicators (multiple slots), what is the logic?
will it buy/sell when only one of those buy/sell conditions are met, or all of them?

TIA
