The Install Time extension makes it easy to locally locate or download and install/update a VSIX file. It also allows you to save the preferred file (URL or file location) to save time pasting it into the prompt each time. You can also specify how many patch versions to attempt fetching if the remote or local copy of the preferred VSIX file no longer exists.
Open the Command Palette and type 'shell command' to find the Shell Command: Install 'code' command in PATH command.

Select a VSIX file within your workspace
Right click on a VSIX file or menu tab of a VSIX file and select the Install Time: Install this VSIX menu option at the bottom of the menu list.
Enter a VSIX URL or file into the install-time settings
Add the location of the VSIX file you would like to use as the preferred extension to update in the install-time settings called 'File Or Url'. Once this is set you can select the Install Time: Install extension from URL or file command palette menu option.
File or Url: This is the preferred file or URL location of the extension you would normally install/update.
Patch Increment Retry Count: This is the number of times install-time will try to fetch the preferred file if it encounters a 404. It will increment the patch number on each retry in case your extension patch version has incremented from the original version you've set as the preferred file.
Patch Install Retry: Enable or disable the patch increment retry count feature.
