The tool Select can be used with a regular expression to perform filtering on most any value that you want. I see the help Guy gave you in the other post, so am not sure if this is still an open question or not, but wanted to let you know about alternative options to the tools in NGS: VCF Manipulation
When working with a VCF dataset, save the header off into another dataset (also filtered out with the same tool) then use the tool Concatenate to place it back on top of the filtered dataset if you are not using tools from the group VCF Manipulation.
