Well, yes. That was my immediate decision. Just to find an
alternative/temporary way and to wait for something more reliable and
standard.
I don't really have the critical need to proceed with such a setup right

feature and what others think and tried/managed to do about it.
I really wanna thank you all for your valuable inputs.
Have a good rest of the weekend.
