Request: Specify interpreter for dedicated console in run config

Edit: Since I had last looked yesterday, a new issue #22020 with a similar suggestion was opened. Feel free to close my issue if you rather have a single issue on the topic.

Request Description

To switch the Python interpreter used for a console in Spyder is currently rather cumbersome by changing the setting (in Preferences > Python interpreter > "Use the following Python interpreter") for all subsequently started consoles. Would it be possible to add an option to the "Run configuration per file" dialog for selecting a specific interpreter when using the "Execute in a dedicated console" option? This would help when regularly switching between scripts that need specific virtual environments as the required interpreter has to be set only once. The default setting could be "Use interpreter in the preferences" instead of a fixed path to retain the current behaviour.

Relevant other issues, PRs, etc.

A similar request #1601 was already placed in an issue 9 years ago, which is still open but not active (I tried to commented there first). Also #22020 was created just before my request.

An easier selection of the interpreter for a new console was apparently implemented in #20421, but as of Spyder v5.5.4 that new menu is not yet available. This also only simplifies the issue for the "Execute in current console" option of the run configuration. A per-file interpreter selection could also apply to the "Execute in an external system terminal" option (I do not use this option, so I am not sure how helpful it would be).

The spyder-env-manager might be relevant for this topic in the future if it is still pursued. Though a per-file selection of the interpreter/environment would still be advantageous.

Specifying the interpreter on startup could be an possible solution by having a link to Spyder for each environment #18805. But running multiple instances of Spyder with different interpreters could become confusing and is not much less cumbersome than switching the interpreter in the preferences.
