Multiple selection of data using ITS URL?

Hi,

Is it possible to transfer mass data Via the URL. For eg for the transaction iW48 i want to multiple order nos (that are not in sequence). in R/3 i can do this by the multiple selection of order option and then specifying the Single values. Is there a possible solution where i can do the same by calling the ITS URL?

Any pointers in this regard would be of great help.

Rgds
