Ignore Digits Property on user input

[rswartzmiller]

In composer on a user input block. I would like to ignore all digits expect for *. I've try the following combination 1,2,3,4,5,6,7,8,9,0 and 1;2;3;4;5;6;7;8;9;0 but neither on of them work, and suggest would be great. What the support doc reads is below.

Ignore Digits Property
Select the variable to contain a sequence of up to two keys to be treated as though the keys have not been pressed

sequence of up to two keys

Documentation clearly states why it doesn't work...
If you want a different treatment you need to create your own grammar and configure it under the input block
