symbolic integral with conditions

Hello all good people, a have one problem, probably not with mathematica but with mathematics :) I'm writing a code where I need to calculate integrals of quadruple trigonometric series (not sure if quadruple is correct term, i mean the series of series of series of series:) Here is simple example with sine function. Problem is that solution should be represented with a lot of conditions (i.e. if n==m==p==q then..., and so on), but it seems that mathematica can not handle it.
Integrate[ Sin[n*\[Pi]*y]*Sin[m*\[Pi]*y]*Sin[p*\[Pi]*y]*Sin[q*\[Pi]*y], {y, 0, 1}, Assumptions > {{n, m, p, q} \[Element] Integers, {n, m, p, q} > 0}, GenerateConditions > True]
It would be great to hear yours thoughts on this.
All the best, Aleksandar
