Regarding option routers

Is there a way of configuring the ISC DHCP server, so that when "option 
routers" is sent back as part of dhcpack it contains the address of the dhcp 
helper address that came with the dhcp request.

My DHCP server is serving multiple L3 subnets and a router connected to each 
of these also acts as the dhcphelper.  I want to keep my dhcp config fairly 
static, but the helper address might change.  Hence, I need the dhcp server 
to dynamically figure out the helper address and send it back as option 

Is this possible ?
