Connecting two Datasets to One Repeater

Hey everyone,

I have a P database collection in Wix of news automatically populating from rss feeds. Now I will connect that with repeater and in that repeater I want to show any random image, because feeds do not have images.

So repeater is already connected to dataset of P database. It has no images. So I want randomly add images into each repeater.

Now it could be done with adding images to Q database and adding reference fields in P database, but content is coming from external source every 4 hours and I cannot add manually all images in each row of P database generated dynamically.

I want to automatically show any image from Q database full of just images, into repeater populated by dataset of P database. I tried many things but cannot come up with anything!

Only solution I can think of is using other repeater of same layout and keeping number of entries same in both.

So do have any solution for this!? @yisrael-wix
