Microbore connections

[copperhead]

Hi all.
Advice would be much appreciated on best practice connection of extra 10mm to 22mm pipe to feed extra radiator. At present, 3 rads on 1st floor piped up using 10mm. Need to pipe up to one more rad in loft conversion. I believe a manifold may be correct option, but not sure of method of connection/types of manifold. Thanks in advance for any advice.

Nothing up with having seperate tee just before the manifolds
