Managing Contact Campaigns: Tips on Limiting Company Contacts in Instantly

I’m using clay to find 3+ contacts per company, but i want to ensure only 1 contact is pushed into an instantly campaign.

1.
how can i ensure only one contact from a company is pushed to instantly at a time
2.
how can i view how many days it has been since another contact or lead from the same company was pushed to instantly
3.
can i set up a cadence that says after x number since another contact was pushed to instantly from the same company, then another contact can be pushed to instantly?
