CLOSURE OF REQUESTS

Dear Helpdesk team

I am going through the demo of helpdeskplus.

i am quiet impressed so far

2 queries are there

1. can i import assets in the same way i import requesters

2. closure of request , is taking the completion of request as present time
but when a help desk agent does this closure, he may do it bit later also and he should be able to do it pre- timed. is it possible

regards
indu
