markers to define a cell population in a single UMAP

Hello guys,

I'm doing single cells analysis using Seurat pipeline and after the cluster distribution (UMAP) I found markers unregulated and downregulated in each of them.
I want to know if it's possible to define in a single UMAP plot a specific cluster by including or excluding specific markers
for example:

Cluster 1: A+B+C-
Cluster 2 A+B-C+
Cluster 3 A-B+C+

Does exist a code that when I give the information (A+B-C+) automatically defines and shows in UMAP the cluster 2?

Or is it possible represent all of three markers in only one plot?

Thanks for help
