Is there a way to specify patches during install ? That is patching an existing package without redoing a package.  

The use case is that I have this patch [1] on ocp-indent that seems unlikely to be integrated (cf. [2]). Now I would like to be able to benefit from ocp-indent's default package updates but just apply the patch before installing.  

Is there a simple workflow to achieve that ?
