How can I persist the modified V4L2 (Guvcview) profile of a webcam?

I have a USB web camera that gives suboptimal results when I plug it in (Linux seems to apply its own V4L2 settings to it that it thinks are best, they are not). Mainly, it operates at a low FPS. But if I open Guvcview, select "Settings" -> "Hardware defaults" in the menu, and add some minor modifications, I can get a higher FPS and overall better quality. If I close Guvcview and open it again, the settings are reset in Guvcview, but the changes I made stay active in other apps like video chat software. However, if I unplug the webcam, the changes are lost everywhere, and after plugging in again I have a worse quality again. What I do for now is I saved the changes in Guvcview as a .gpfl file (menu -> "Settings" -> "Save profile"), and whenever I reconnect the webcam, I open Guvcview and load the profile with "Load profile". How can I make these settings persist so that I never have to do this again, and have them applied to only this specific video device and not others?
