Feature - Relation between controls?

Hey Guys, will it in the future be possible to make some relations between controls?
We have our controls divided in 2nd line controls and 1st line controls. 1st line controls are normally controlling the effectiveness of operational Things like antivirus, firewall settings, Network etc.
2nd line controls normally verifying the 1st line controls. therefore it could be nice if it was possible to make some relations opportunity from one control to another (for us, from 2nd line controls to 1st line controls)

Just a quick thought here - would you be able to collapse those two controls into a single control, and use either the Maintenance or Audit functionality for that control as your “verification”?
