hidden handles for shower drain (TECE Drainline)

To maintenance my own designed drain strainer in the shower I need to lift the cover up. Everytime I want to do this while standing in tn the shower, the needed hooks are not in range... So I thought id would be nice, if the hook are always in place but inconspicuous too.
