ADDITION OF "REQUIRED" OPTION IN BUILDING BLOCKS TAB

Hi
I think it's very important if it's possible you make an addition of "Required" option to building blocks tab and specifically to sections "signals (predefined conditions)", "indicators" and "stop/limit entry blocks"
It would be very useful this, because this way someone could make more precise use of some building blocks of above categories (indicators, rules etc.) as always necessary in building process of strategies and filtering and exploring as much more is possible individual use and combinations of the above parameters.

Example: Let's say I want to use in building process just only "EMA indicator" and all "signals (predefined conditions)" and "stop/limit entry blocks", but to generate in my library only strategies which include the EMA indicator in order to filter and evaluate only these strategies which include the above indicator. As it is SQ now if I will choose all these parameters, I will have a lot or results which combine as rules all the "signals (predefined conditions)" or other "stop/limit entry blocks" and not at all the "EMA indicator".
I think this addition can make the described building process more quickly and efficiently.

Thank you
