At ELLX Taxi in is only available via Lima or Lima 2, Lima 1 and Lima 3 are only for taxi out. Today i got the Taxi in Route via Lima 1.

Unfortunately, this type of data is currently not available in MSFS - if it is added in a future SDK update - we will certainly look to support this type of data, BATC will still organise aircraft taxiways to reduce conflict. As this is a data limitation, I will close this suggestion.
