Integrate[#, {z, clow, chigh}] & /@ (a + z + s[z])

=============
I have an integral involving constants and an 'unknown' function.  I
would like to expand it out to solve for the constants and keep the
integrals of the unknown function as expected.
i.e.
Integrate[a + z + s[z], {z, clow, chigh}]

I want to get out:
(a*chigh + chigh^2/2 - a*clow - clow^2/2) + Integrate[s[z], {z, clow,
chigh}]

However, FullSimplify, etc. don't seem to do anything with this.  Any
ideas?
