Delete words instead of delete line

In our current mud thats have some prompt line is very annoying but cannot be cancel. currently I only black the color of that words, but it still annoying, can any function can delete the specific matched words on a line instead of delete the whole line? and will is influence the trigger fire status on same line?

Example:

Original line -
hp:1250/mp:500> You just wake up.

# currently I black the color of the prompt, but still looks as below:
> You just wake up.

ideal output -
> You just wake up.

# and I still want this pattern can be fire by other trigger.

Any suggestion?

remark:

(the current case outlook)

Original line -
hp:1250/mp:500> You just wake up.

# currently I black the color of the prompt, but still looks as below:
. > You just wake up.

ideal output -
> You just wake up.

You cannot alter the current line. What you can do is omit it, and then replace it (using Note or ColourNote) with an amended version.

People do that to tack on mob statuses, that sort of thing.
