I noticed that SD generated FPL's through Slovenian airspace will never be accepted because SD uses 'coordinates' rather than official entry/exit points. (I had one unaltered SD generated plan rejected recently for this reason). Slovenian AIP:

REF AIP SLOVENIA ENR 1.10 PARA 1.3. B. SPECIALARANGEMENTS FOR IFR AND VFR FLIGHTS (ICAO NOTIFICATION OF DIFFERENCE) FLIGHTPLANS WITH FLIGHT ROUTES CROSSING FIR LJLA BOUNDARY OR VOLUMES OF CONTROLAIRSPACE SHALL INCLUDE OFFICIALLY PUBLISHED ENTRY/EXIT REPORTING POINTS.COORDINATES OR ANY OTHER NAMES ARE NOT ALLOWED THEREFORE SUCH FPL WILL BEREJECTED.

.. not sure what we can do about that in SD. I guess we have to remember to make manual changes to the plans.

Is it really so difficult to make this an option?

A‌s a pilot based in Slovenia, I can say for certain that co-ordinates are not accepted here in a FP. Here's a response I received this morning:

"FPL S5DJJ-LJPZ1115-LJBL NOT ACCEPTED
REF AIP SLOVENIA ENR 1.10 PARA 1.3. B. SPECIAL ARANGEMENTS FOR IFR AND VFR FLIGHTS (ICAO NOTIFICATION OF DIFFERENCE) FLIGHT PLANS WITH FLIGHT ROUTES CROSSING FIR LJLA BOUNDARY OR VOLUMES OF CONTROL AIRSPACE SHALL INCLUDE OFFICIALLY PUBLISHED ENTRY/EXIT REPORTING POINTS.
COORDINATES OR ANY OTHER NAMES ARE NOT ALLOWED  THEREFORE SUCH FPL WILL BE REJECTED.

O‌k, I understand that I can manually alter the field, but this takes away the convenience of using SD for the submission - it's simpler just to submit the plan with a phone call‌.
