Custom web address for accessing articles through DOI

When I click on the “open” button next to the DOI of an entry it opens a web browser to the address https://doi.org/[DOI], which then redirects to the article website. In order to access articles in subscription-based journals, my institution has a shortcut that involves modifying the address to the doi site (e.g. for my institution it is https://doi-org.ezproxy.lib.uts.edu.au/[DOI]). It would be great if the address used to access the articles through the DOI could be modified in the preferences.
