How to change labels on top of PPM screen

Hi,

Is there a way we can remove the lables “Initiative”, “Item”, “Project”
that show on the top left of the Initiative, Item, and Project Screen?

For an Initiative named “ABCDEF” for instance, the screen at the top
left shows:

Initiative: ABCDEF

How can I remove or rename the label Initiative (and Item, and
Project)?

Thanks.
