Mass affect client specific settings

hy - i disabled image backups - because in my lab so many clients will immediately start to image - i only want that a specific client will start the creation of an image immediately

So my question is - is it possible that a server admin is able to start a image backup manually even if the function is disabled ?
perhaps this could be done if i can change all client not to image
so i can “select all” clients - disable image creation - and than i can change a specific client to image.

also fo other settings this would be nice
can this be done easily?

kind regards

it looks like that i have a temporary solution -
i just disabled “Interval for full image backups” -and after most clients gets this setting no client will do aimage backup - but i can start a manual image backup.
