Random Groups: signal/indicator default randomized parameters not available in random groups

Problem:
Random groups are great except I cannot emulate the builder default functions for all the input variables of the indicators I choose. When I use random groups I am forced to input also the ranges for each input variable but some input variables do not allow any random range in the context of random groups. For instance, I cannot add fibo to a random group and then allow a random fibo level. The fibo level is static if put in to a random group. If I was using default builder outside of random groups the fibo level can be random. Same for the "calculated from" (close, typical, mean, high low etc) and same for other drop down selectors.

There are two possible solutions:
1. Allow an option within random groups to inherit all the input variable randomization ranges and steps from the parameter settings of the signal that are set in the building blocks list.

2. Allow parameter ranges within random groups to be set for every single input variable type including drop down selectors such as the fibo level or the "calculated from"
