Possible to combine query Category with Include post by ID?

Hi,

Can I query for a "category" or "include by post ID"?

The result would be both the posts in the category, and the posts with specific IDs, even if they're not in the category.

I tried the following, but it didn't work.

• Category: XYZ
• Include by post ID: 123,4534,5565

No posts. Queries work on their own, but can they bey combined?

thanks!
