[opensuse-buildservice] is there a command like merge?

for example, i branch php package from opensuse11.3:update,  just change the --disable-debug to --enable-debug in php.spec. is it possible to update my package with the original opensuse11.3:update ? -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-buildservice+help@opensuse.org
