ai flight plans / airfield taxi to runway.

[kenlivia]

Hello, Maybe someone may help with these questions please ?
I am very new to making flight plans and have a four double legged plans operating. Using aifp v3.2 with Win7. The aircraft in situ tend to move around the field from their parked up places at the times designated for departures / arrivals. I am thinking perhaps i should apply some sort of taxi instructions to take the acs from parking to the runway ? If so, how does one do this, and where does one apply this extra info into a flight plan. Secondly, i now have 4 traffic blg,s for the same field but different aircraft- How does one put these collectively into one traffic blg.. Just learning this stuff and keeping the plans simple till i have some degree of competence. many thanks
