When creating a Multi configuration job, you can create an axis with name including "-", for example:

axi-name and there is no error validation warning that is invalid.

Create a "Combination filter" :

(axi_name.toString().contains('1') || axi_name.toString().contains('2'))

When you try to save it you get:

Besides that, if you use underscore you can solve the problem, for example: axi_name

And the combination filter: 

(axi_name.toString().contains('1') || axi_name.toString().contains('2'))
