Increase parameters max number for 'DesignerFunction'

On more than one occasion I had to refrain from using the Custom Function” feature because of the limit of 4 parameters.

It would be useful to increase this limit to at least 6 parameters or better yet, eliminate the limit using param arrays.

Thanks for the suggestion - a sometimes viable workaround is to work with separated items to mimic more parameters (sth. like “AppendStrings(“string1|string2|string3”)” would be a trivial example). But I admit that this is less-than-perfect in many scenarios.

Yes, I know that there are many ways to get around this, but it would be difficult to explain to end users who are not developers.
