[U17] Push Changes of Item Type Properties to all Title Blocks/Elements in file

Hi everybody,

i have a file with several sheets and title blocks (imported from a .dwg). The title block information came in as item types. 

Most of the properties like project number, project name, etc. are identical across all title blocks. A few properties are different across the sheets (e.g. scale, sheet size, etc.).

Is there any way to update all identical item type properties across the file? For example define default values in the item type editor and then push those values to the titleblocks.

The only workaround i found is to detach and reattach the item types to the title block.

Is there any better way?

Greetings,
Florian
