I actually had to fly the scenario you are describing last year. I was coming in via AKIKI, so the route was ammended to KATHY-ELDER-OLGUD-TARAN-BEWLI.
Although in general holding anywhere is not a problem (as some people have pointed out on the other thread), arrivals via this route are faced with some extra difficulties. Firstly, there is no defined STAR this way, so we have to type in the waypoints individually as you rightly point out. Secondly, we are not familiar with the waypoints as we don't normally fly to them so OLGUD (in particular) proved a bit of a pain to get into the FMS as it took a while to translate the spoken word into a correctly spelt word. It would have been quicker if OLGUD had a real/more obviously derived name eg. HAZEL.
In themselves these problems are not too serious, but combined with instructions to slow down and stop descent and EATs being issued etc, things did start to get a bit busy. A rough guide to the key presses required:
O L G U D (line 1L) (EXEC)... T A R A N (line 2L) (EXEC)... B E W L I (line 3L) (EXEC) (HOLD) (line 3L) 0 8 5 L (EXEC). I suspect that there would then follow a discussion as to whether it was a 1.5 min hold at BEWLI or not. Don't forget our keyboard is not qwerty either!
To solve the problem completely, someone from Ops could assign a STAR designator to the route then you could save some RT and we would have the waypoints in the FMS, and in the short term an initial heading whilst we find some of these places would be great or even direct BEWLI (FMS equipped aircraft should stay within the protected holding area regardless of entry procedure).
Interestingly, these problems are not shared by CLN or DTY (or whatever number they are now) because the en-route holding occurs at places on the STARS. TopBunk's comment about the FMS knowing the published hold axis and direction doesn't apply to our 757/767s as it always defaults to RH holds and uses the course you are flying into the fix as the holding axis unless we change it.
... and I'm sure you issued an Onward Clearance Time didn't you??????!!!!! (MATS 1 Sec4 Ch2 P6). (I'm only teasing, but when we are given an EAT whilst we are holding en-route there is often a query as to whether this is from the inner hold or the present hold).
