Is there any chance that I can copy and paste only specific components from previously published versions to current without reverting everything?
Unfortunately not at the moment, but as a workaround, you can do the following
Save/publish your current version so that you can restore it later
Restore your old version that you want to recover
Clone the project
Now restore your initial current version
Then you can follow the steps described here to copy and paste components from the old version. Deployments and automation | Learn Plasmic
