 That's Gentoo, honey.
 I got 3 but I could have 10, 20, or a billion.
 I can select:
 [~]# eselect python list
Available Python interpreters, in order of preference:
   [1]   python3.11
   [2]   python3.12
   [3]   python2.7
 Python 3.11 is first because that is the current Gentoo
default.  But I can switch between all versions at will
via:
 eselect python [1 | 2 | 3]
 Can you do that with your crippled distro?

Of course
update-alternatives (basically manages symlinks)
https://www.baeldung.com/linux/update-alternatives-command
//current
wsl$ python
Python 3.10.12 (main, Nov 20 2023, 15:14:05) [GCC 11.4.0] on linux
//install new python
wsl$ sudo apt install python3.11
Setting up python3.11 (3.11.0~rc1-1~22.04) ...
Processing triggers for man-db (2.10.2-1) ...
//add 2 python entries to the update-alternatives app
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.10 1
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.11 2
//choose which python version you want
~$ sudo update-alternatives --config python
There are 2 choices for the alternative python (providing /usr/bin/python).

Press <enter> to keep the current choice[*], or type selection number:
//new python version is the default
wsl$ python

You can set and choose from multiple versions of the same program (as above), or multiple programs assigned to the same name (like 5 different apps assigned the name 'editor'.
On Windows you could create a folder of .bat files with names:
editor.bat
image.bat
newsreader.bat
And inside each one list the related executables and REM out the ones you don't want to use for the time being.
editor.bat
REM "C:\Program Files\Notepad++\notepad++.exe" %1
REM "C:\Windows\SysWOW64\notepad.exe" %1
"C:\Program Files\Sublime Text\sublime_text.exe" %1
Add the folder with the .bat files to your path
Then from any location enter
$ editor file.txt
and it will launch the designated app and open the file in it
