COPR mechanism to apply patch to linked spec, prior to build?

[PGNet Dev]

i regularly create COPR projects, which link an upstream repo .spec in a pagure project.

i want to build @ COPR _after_ modifying the .spec.

there are 2 ways I see doing that.

	(1) manually modifying/patching the spec itself
	(2) having the buildsys auto-apply a patch to the spec, prior to the build

(1) is trivial, _if_ I edit a _fork_; that interferes with workflow, breaking upstream
source updates' triggers for autobuilds at COPR 

(2) is doable at opensuse's OBS, specifying the patch to be applied to the link-ed
project sources

e.g.,

	https://build.opensuse.org/package/view_file/home:pgnd:devel:gcc10/gcc10/...

what (other) mechanism exists for applying patches to a COPR spec, prior to build?

is there an OBS-style functional equivalent?

You can trigger the custom build (shell script) [1] using the custom webhook,
and do whatever you need to (clone repo, apply patches, etc.).  It's not really
an equivalent, so  -- as I understand it -- most of your requirements are
specified in upstream ticket: https://pagure.io/copr/copr/issue/1441

seems I keep bumping into the same issue!

re-reading that lengthy RFE & re: webhook scripting ... 

the examples refer to copr cmd line setup of the scripting.

to verify, that _is_ the same functionality as

@ online, correct?
