How to install multiple of the same software using on NixOS with flakes, preferrebly configured using home-manager?

I’m looking to install multiple of the same software like vscode/vscodium/firefox et cetera. Each having a different configuration.

Currently, this installs microsoft’s vscode.

# home.nix
programs.vscode = {
  enable = true;

Using the package option sets the source to vscodium but how would I do this simultaneously with the above.

# home.nix
programs.vscode = {
  enable = true;
  package = pkgs.vscodium

If I set both of the together, I get the following error. on nixos-rebuild command.

Is there a way to install multiple of the same applications, with and without the same version number and commit hash, with different configurations with a custom name like VSCode-1, VSCode-2 and so on? Thank you for any assistance.
