You are limited to two stopovers in the continent of origin
but there is no limit to the number of stopovers at the same place
Good idea to point out the possibility of adding another trip at the end (which could of course be at the beginning instead)
Using the OP's first itinerary for example:
LHR-xHKG-BKK....BOG-MAD
stopover and return to LON on a separate return ticket
then later
MAD-TLV-LHR
