That is my work around for now... I added a set of custom waypoints in the REF page according to the approach charts and everytime I will need to manually enter the waypoints into the FMS, does the job fine enough. However I was not able to capture the localiser until like 10 DME and glideslope only at around 6-7 DME, still have to do a big chunk of the descent manually, not sure if this is a Navigraph error or something related to the plane itself.
