The Feature about signal generators.#3578

I would like to request the ability to use special characters and wildcards, such as ““ and “?”, when specifying item codes in the signal generator.
For example, I would like to be able to input “u——“.

If we could input regular expressions, that would be even better. :)
Like this “(R|C)u–(Su){2}”

Signal has a Wild card character for example:
Shape Ru–Ru–:–Cu–Cu:——–:——–
matches some Signal like Ru–Ru–:XxXxXxXx:——–:——–:

where X is any shape and x is any color

other examples: XrXrXrXr all quadrants are red but any shape
RxRxRxRx all are Rectangle but any color
cxcxcxcx crystal any color
