How Can I enable/disable Physic collisions with specific conditions

I Faced today an issue that the enable/disable physic collision action doesn't trigger by the conditions I set, even I thought it's bug, but it was missing feature that I wrote about in github

https://github.com/Scirra/Construct-feature-requests/issues/389

LSS

Here's simple example to explain my issue that I hope someone give me solution for:

In the following example I made simple event code that trigger all of Balls entites with 100% opacity to interact with the player physic otherwise it will be disabled.

The result is that each ball entity collision will be disabled for the player in this case. Unfortunately, this doesn't work with any criteria like scale, variables, opacity, etc.

For a longer explanation, please visit the GitHub page, which even has an example C3P project. If you're interested in helping fix my issue, I would greatly appreciate it, as it affects a critical mechanic in my game. Thanks!
