Manual Deactivate warning for some blocks

In my taskbot it is expected that some "save web elements" must not find anything and therefore the corresponding cell in the table must remain empty. I would like to have the possibility to manually deactivate the warning for these specific blocks (not all, but only some of my taskbot) so as to only receive the warnings on the others and have to worry if I receive them, instead now I have to manually check the log and see every time if the warnings refer only to those blocks or if there are warnings also on other blocks (which actually interest me). I don't know if I explained the problem clearly...
