Weekly (or every other day) Digest Post preferably for more than one RSS

I’m hoping someone can help us out. We have RSS feed of our items that we are selling on several different sites (so several RSS feeds) as well as RSS feeds of several external blogs that we want to do a digest post for occasionally. We have been doing this manually but it is labor intensive and would prefer to have an automatic digest via a wordpress plguin.

We are currently using Digest Post (https://www.ads-software.com/extend/plugins/digest-post/) but we cannot figure out how to customize this to be what we need.

Specifically, this is our ultimate wish list but if someone can help us to do any of these things, we would appreciate it:

• Ability to specify more than one RSS feed (with possibly different terms (frequency, limit, etc) for each)
• Publish at a frequency that we set (IE, weekly or every three days)
• Ability to specify to only post the digest if there are x entries (IE, a minimum of 3 would be required, otherwise it would wait to post until it reached 3)

Our questions is two fold. If it is possible to modify Digest Post to do what we need, what do we need to edit?

If it is not possible, can anyone recommend another RSS digest post plugin with more flexibility.

Thanks!
