Thank you for writing and for the follow up.
This is exactly how to reuse theme settings. The whole idea behind repository items is make styling easier, faster and less resource consuming. We strongly recommend putting all possible settings into repository items. This not only allows you to reuse them but also makes it easier for one to quickly review what is set for a given element/state and allow you to change settings at one place.
If you have other questions, do not hesitate to write back.
