Inter-App Audio on multiple tracks

Here’s how it should work but does not.

Load one audio track instance of SampleTank In track 1
Create as many audio tracks as you wish to record from sample tank when needed.
Arm track 1 and record input from sample tank
After your done go to track 3 arm and now record from sample tank to this track etc… and so on

Sample tank is you audio source
All other tracks receive audio from sampe tank when they are selected and have chosen sample tank as its input. (No need for multiple instance) and Cubasis should not complain about us selecting SampleTank or any other audio app mulible times as an audio track input.
Also this is been along time coming and am very disappointed we don’t have this by now, is the ability to send an audio of an app to say channels 3-4, 5-6 etc…
Then on another track choose channels 3-4 or any other as an input.
This wold solv a lot of problems
