How to apply lambda layers WITHOUT deleting other layers that already exist?

Hello, so i’m trying to apply a layer to all of my functions,
the thing is - there are layers that are already deployed there (that are managed outside of the serverless framework).

when specifying atleast one layer on the sls.yaml - it totally deletes the other layers.
is there any way / other plugin that can just add / update the layers i’m applying without a total replace?
