How do I specify a new location for each build within one instance of a FINN-docker?

Hello,
I have been meaning to run some tests on a model to compare resource usage, understand how the flow works, and examine the effects of customization on the output. The tests involve changing factors one at a time and are not iterative (they are independent). Typically, I'd want a way to run each test's files in parallel. However, I wish to isolate the temporary files generated by each run. The issue I am running into is that all the builds generate their TMP files to a single location. What I wish to isolate is:

1. HLS code specific to the model's configuration (PE, SIMD, etc).
2. RTL code generated by the model.
3. Zynq project and stitched IP generated by FINN.

In short, I would like to create a single FINN Docker instance, run multiple notebooks in parallel, and store temporary files in a custom location assigned to each notebook. I know how to specify locations for output files, but not TMP files.

I am aware of the FINN_HOST_BUILD_DIR environment variable. However, that specifies the location for the Docker instance, making it global across all notebooks. Is there a way to specify the location during runtime?
