Task functionality

Hi there! I love Zoho Projects. thanks for making it!

It would be really great if there was a way to set the "billable" "non billable" setting of task so that when it's chosen on the timesheet, we don't have to manually adjust it each time. (I've often forgotten and it's a hassle to go back and fix this).
For example, I donate marketing work to nonprofits and though I like to track the time I do for them, each and every time I need to put "non billable".....not a huge deal, but just one extra step each and every time.

If we could either designate the B/NB status of a projects, task, or milestone when we create it, it would save time for later.
(btw: I keep a lot of tasks up over time, never crossing them off because I use them to track activities on the time sheet...many of my tasks are ongoing.........I thought you should know that. It may not matter to people who merely check off a task one time and it's gone. But, there has to be other people out there who leave tasks open for long periods, like me.
...for example, I have "PA work" as a permanent task, so as to enter the work on my timesheet for a particular client.)

ok, thanks! I hope that all made sense. =)
