importing many transport requests together

Hi,

If I want to import many transport requests in STMS, one after another, is it ok if I select them with 'F9' and then import them all at one go? Also, if I do so, do I have to select any special option for transport while importing the requests?

Or it it advisable to import them in the normal way i.e. one after another?

Thanks and regards,

Kunal.
