DTP Activation for SPO

Hi Gurus,

Due to change in SPO - I need to activate 500+ DTPs.

The DTP activation wizard in SPO makes you click on each on every DTP activation and it takes long time to activate individual DTP.

Another option is change/activate each DTP through RSA1, which takes little less time than wizard.

Does anyone know a better way (mass activation - for specific SPO) of the DTPs?

Thanks in advance.
