titleblocks

I have a large technical drawings pack in onshape and I have realised there is a mistake in the titleblock. Is there a way to edit the title block and have it apply over the whole document similar to 'edit sheet format' in Solidworks, rather than having to edit each sheet individually? In my opinion, elements on the title…

I am trying to create my own title block and struggle aligning names, dates etc. inside each cell. Is there a way of keeping a standard or all need to be placed by eye? Thanks to everyone.
