Conda: stacking environments

[masonk]

I am trying to set up a monorepo that uses stacked conda environments, let's call them 'base' and 'subproject1'.

The intention is to use conda's stacking facility so that subproject1 is stacked on the base environment. The base environment will contain some really basic conda env, like the code formatter we are to use throughout the monorepo, as well as an installation of a "development package" of the monorepo itself.

Stacking conda env works well from the command line, but Python: Select Interpreter -> choose subproject1 activates the env without stacking it onto base, even if conda is configured to autostack (conda config --set auto_stack 1). This makes sense because there's no way to tell VSC which env to stack onto.

Is it possible for VSC to adopt a stacked conda environment in anyway?
