Add a new macro (icon) to your toolbar – in fact two macros (tool buttons) – one for selected objects and the second for all objects:
[FlattenSel]^C^C_UCS;;_select _move _p;;0,0,1e99;;_move _p;;0,0,-1e99;;
[FlattenAll]^C^C_UCS;;_move _all;;0,0,1e99;;_move _all;;0,0,-1e99;;_chprop;_all;;_thickness;0;;
Do not use on 3D solids as it may distort them
