How to aggregate multiple RSS feeds to use in a single scenario?

Hi, I’ve got multiple scenarios starting with an RSS trigger when a feed is updated. Given that at least a couple of these scenarios are pretty similar to each other, is it possible to aggregate the corresponding RSS feeds so that I can use just one scenario and not waste operations?
I looked online for some RSS aggregators (like RSS Mixer), but their base plan is pretty weak and they update very slowly, so I hope Make has a better option.

Thank you in advance for your help
