Best way to show installed LTIs in the App center?

I just finished a support request claiming one of the LTI Apps installed in our root account was broken - in fact, what was broken was that the instructor had installed a second version of the LTI into their course - I'm assuming they didn't know the app was already installed -- if the instructor had looked on the "view app configurations" they would have seen it, but I don't think most users would do that.
Another thing that seems troubling is that even though some apps (but not all) will show in the app center as "installed" if a user clicks through to the details view with the grey "Installed" box under the LTI logo - there is a much more visible +Add App button underneath which will allow the user to attempt to install the app again (and when I think through it as a user who understandably hasn't already noticed the disabled Ares link in their navigation choices, clicking +Add App seems like it would be the thing to do to add Ares to my course) -- in the case of Ares (we self host a server that has custom details) an instructor clicking +Add App will be a guaranteed disaster.
The problem seems a little more complex, but I don't want to TLDR people - my main points of inquiry/hope are:
- Can the +Add App button be disabled for installed tools in any way?
- Does anyone out there create "custom apps" that would appear in the app center for tools that don't show up there, or which are there but not correct? (e.g. I was considering using the whitelist to hide Ares but have custom version that would hopefully show up instead - although if I can't disable the +Add App button, I don't know if it will save us any future tickets...)
- Is there a way to associate apps that should be connected to an app in the app center after the fact?
Thanks for any solutions/experiences/ideas you may have to share!
