Keywords alternative to sync between LR and LR Classic

Hi,

I am using LR Classic to organize all of my Photos, actually more then 200K. To enable a homeworking worflow I am syncing all the projects I need and then use the LR cloud version to edit those pictures.

I need to add some keywords to LR cloud that I can use on the LR Classic for organization and export full res pictures.

Actualy I am using stars and pick option that are synced between the two apps. But I need something Like: Pics Selected to Album (keyword) to work between Cloud and Classic versions.

Any tip of workaround for me?

I am using the latest version on both apps.
