Does an Interact (1) action have a single target?

[Serigala]

Starting with the usual disclaimer , that I have tried the search and the indexes etc, with no joy...

...does it state anywhere that an Interact (1) action can only have a single target?
If I place a treasure counter next to a terrain feature that I am targetting with Sabotage, such that I can place a model in base contact with both, can a single Interact (1) action complete both schemes?

If it is allowed by RAW, is it reasonable, or taking advantage?

You must take an Interact action for each separately.

You would not be able to declare Sabotage on a terrain feature that had the Treasure as the Treasure is supposed to placed in the center of the table, while the Terrain Feature for sabotage must be completely on your opponents half of the table.

Thought so...
Is that in writing anywhere? Or just rules as intended (and commonly played)?

Not the point of my question...I could just as easily have suggested the objective markers used in Claim Jump or Destroy the Evidence...

...but if the terrain feature is 1" into the opposite half of the table then it would be quite easy for a 30mm base to be in contact with both the treasure counter and the terrain.
