Generating different schemes for 1 target

Hey guys. I'm trying to implement configuration which will allow me to generate multiple schemes per one target. What i need is to create few schemes that each has different test targets linked as well as different configurations applied but actual target should stay the same.

I have tried configVariants but it only allows to create multiple schemes with different configurations, but the list of test targets stays the same for each created scheme. That option doesn't allow to solve my case.

I have also tried to use Scheme Template but it only allows to create 1 scheme per 1 target. Any attempts to pass not existent target name to schemes: failed. XcodeGen requires each entry in schemes: to be equal to existent target name. So when i try to pass the same target it simply rewrites last setup and creates only 1 scheme. So my case where i need a few schemes for one target can't also be satisfied with that mechanism.

Help me please, all i want can easily be imlemented in XCode by tapping Manage schemes, selecting my main app's target scheme and tapping Duplicate. Then i can configure scheme how i desire, but i can't seem to find solution for my problem in the current XcodeGen specification....

Start by reading XcodeGen's scheme-template and configVariants handling, since the issue identifies both as related entry points. Determine how scheme names are keyed and how test targets and configurations are assigned. Done means the specification can generate multiple distinct schemes for one target, each with its own test targets and configuration, without overwriting another scheme.
