how to add old builds which are rejected for testflight

Question

I have an app which is rejected for multiple times stating Apple can't check the app as the app is not loading beyond Splash screen.

When I check it at my end, its working fine with no issues.

So now what I have decided is to check through the TestFlight. For that I upload new version of app with build as 1.5.4.5 and its working fine.

Now I am looking for a way to add 1.5.4.4 for testflight, however I can't.

Can someone point me in right direction on how can I add those old builds for testflight? I want to check those builds at my end on multiple devices.

No, you can't use an old version as the build number must increase, you can checkout old code and make a new build from it then upload that.
