You could use hidden fields in the form to store status
<input type="hidden" name="status" value="put status info here ">

I've made this work quite well in a search screen. If you need lots
of status you can of course add more hidden fields - status1, status2

(BTW why can we only have 1 submit button per form - allowing more
would improve the quality of forms interfaces no end, and doesn't
seem technically difficult?)
