Butler: distinguish a letter from a number

Question

Hi,

I have eleven cards with number starting names in a board and I want to change only this cards.

Command I´m looking for:  `when custom field "STATUS" is set in a card with a name starting with a "number" instead a letter, for each card linked in the attachments ...`

What is the correct way to write the command how expect a {number} an not any character {*}?

If does not exist, any idea how to make it work.

@Gonzalo Zapata there's an (as yet) unpublished feature that allows you to use regular expressions, so this would for example match only cards that had a name starting with a number:

when custom field "STATUS" is set in a card a card with a name containing "regex:/^[0-9]+.*/" for each card linked in the attachments ... etc.
