SUM SP 16 manual directory option

Hi,

I'm using SUM 1.0 SP16 to update the single sca file in JAVA stack of PI System. I'm giving following commands

STARTUP confighostagent devwp_update SID=XIM user=ximadm

http://hostname:1128/lmsl/sumabap/XIM/doc/sluigui

After giving above commands i get SUM screen which asks for stack XML file.

How can I get manually prepared directory option

Thanks

Vishal
