I think there are only two ways to do this: append "@IP" to every
test; and define FPING to be "xymonping --source=IP".  Obviously, the
latter only works with ping/conn tests, and I don't think it gets used
if "--ping" is on the xymonnet command-line (in tasks.cfg).  From
reading the source code, I can't see any other mechanism for
overriding the O/S-provided address.

There's probably a way to do this using policy routing.  If a policy
route is selected, and the "src" hint is defined in the route table
entry, then it will be used for the source IP address.  A route table
entry can be selected based on a "mark" applied by netfilter
(iptables).  You can mark a packet based on things like the PID, UID
and GID of the process, and the process command-line.  It sounds like
a lot of fun, but it's not something I'd want on my networks.
