"Select Data" modelbuilder question

I am new to modelbuilder. I have a geodatabase with over 400 layers. I would like to select a subset of the 400 and merge them into one layer. The subset have the same suffix, but different prefixes, in their name.

How do I select multiple layers with the same suffix? The modelbuilder select data tool gives me a list with individual layers found within the geodatabase, but I want to select specific layers by the suffix name at once e.g. %_xyline or *_xyline.

Thanks!
