I'm faced with a peculiar problem. A customer has a sandbox Dynamics 365 instance (online) with... a LOT of resources (probably due to installed apps / 3rd party solutions). By itself, this isn't a problem.
The issue arises when I'm trying to make a new solution for said customer - they want me to fix a bug or change an existing feature. If that can be done via plugins - great, no issues. BUT if this involves modifying an EXISTING resource (like a JS or HTML) then I just can't add these to a new solution (for clarity). The reason I can't add them is because there's over a 1000 resources, and the "add resource" screen has no paging, showing all the resources in one HTML, effectively killing my browser. I've tried it in IE and Chrome - but I don't think it matters what I try this with, the result is that the page just dies (client-side) due to the number of records on display.
I'm wondering how to solve this problem. XrmToolbox doesn't have any plugins that would help (there's a generic "copy solution" plugin, which is too broad). I could create a console application to manage the resources from code - since I've already did things like this in the past, I know this would work, but is additional work that I'm not sure the customer would appreciate being billed for.
Are there any other ways to manage solution components that I'm missing?
