Assembler: possible to disable automatic evaluation of output expressions?

Hi! Is it possible to disable the automatic evaluation of output expressions, so that they are only evaluated when pressing the "re-evaluate outputs" button?

Context:

When simulating sweeps I often face the situation where some output expressions fail to evaluate when Assembler tries to automatically evaluate them, but evaluate correctly when I use the "re-evaluate outputs" button once all the sweep simulations are finished (usually this happens when I have ocean and/or Matlab outputs defined in those tests, so I always assumed it had to do with some causality issues that vanish when all the points are done simulating).

The problem is that now I have some tests with very heavy post-processing outputs, and when running long sweeps the automatic evaluation of those outputs takes significant CPU resources, to the point that it interferes with the actual simulations, which then take unnecessarily longer to finish. And, what is worse, it's all useless because the actual outputs still fail to evaluate because of the aforementioned causality issue. So I anyway need to re-evaluate everything once the sweeps are done.

Thus, I would like to disable the automatic evaluation of all outputs, so that they are only evaluated when I manually press the "re-evaluate outputs" button, once all simulations are finished.

Is there a way to achieve this effect?

Thanks in advance for any help!

KR, Jorge.
