Use caps lock (also as) as a modifier

[3v1n0]

Hey, I'd like to map some CapsLock + keys to other combinations, while at the same time I want to preserve the normal usage of capslock when tapped normally.

Now, using simple things work (e.g mapping Caps lock + h to key_left, but the problem is that the actual capslock status gets activated and never restored.

So I was thinking to instead map it to Caps lock + h to Capslock and key_left, but still it doesn't seem to work.

Is there a way to make such event to be even forwarded when used as modifier?
