I suggest to add the ability to upload the package.xml manifest files to populate the metadata filter before the comparison step of an org to git or org to org deployment.

A lot of Salesforce developers use package.xml files locally to deploy some parts of the functionality in order to speed up the deployment process.
Currently, Gearset allows you to select the components via Custom Filters, but it is slow to select about 20 components manually. Uploading the package manifest from the local machine can speed up the process very much,
