We need an IGNORE THIS SHOW option

One of the ways that I control which programs my PTV records is by going through the Replay Guide and doing a Search For Matching Shows in the Replay Channels. This action produces a list of shows that matches the keyword(s). I can then go through the list and do a Record This Show on the programs that I want. If, in addition to the Record This Show option, I had an Ignore This Show option, I could be extremely efficient in the use of what limited disk space that I have. Currently, I have to play games with the Change Search Options and the Categories functions to accomplish the desired result. It takes 5 times as long to do it this way. It could be much, much easier.
