Limit RSS feed imports being auto-post to social channels in one hit

Can you limit the number of posts being auto-post to social media channels?

I am currently sending post to my social media channels but they are all be post at one time. This is making my social media posts appear spammy. I'd like to be able to autopost a RSS feed in a cycle. For example, Monday - Feed A, am post, pm post, Tuesday - Feed B, am post, pm post, and so on.

Any thoughts?

Cheers,
Andrew
