Mass change on Standard Network

Hi Experts,

Is there way to make mass change on Standard Network? like the mass change option we have on operative network/project?

Ask asking without using lsmw ect. some standard way similar to CNMASS ?

For this customer we have huge standard network templates with activities and activity elements. They have user fields with lot of data. So wondering if there is mass change option to update fields/values in the std network.

Thanks,

Krishna
