Cloning shipment methods problem

[bart1983]

J3.9.0 VM3.4.2
I was able to CLONE about 175 shipment method and every thing was all right until I try to change in DB groups for newly cloned methods.
While cloning (shoppergroups on clonned shipment methods where set) there is no set to __shipmentmethod_shoppergroups for newly cloned methods (same as old cloning methods or even empty), there is no even entry in DB in __shipmentmethod_shoppergroups for newly cloned methods, even empty. And now I have to create 175 table entries which should be clonned too.
That is happen on test platform so no stress but the question is if that is normal or a bug. If a bug so how to fix it, because in a second i'll need to do that operation on product platform.
Only this table was not updated (by clonning). That all cloned methods have entries for one group (I understand that ALL GROUPS have no entry in that table).
Or there maybe should be bulk assotiation to group? Or something.

No other method as using 175 shipment ?
