Simplify the way and & or is used in reporting

Currently if you wish to use the 'or' statement in reporting if there are two fields you need to look for, you have to repeat all the filters except the different field you need to look at. This is time consuming and makes this more of a manual process. Firstly it would be good to be able to copy ll the filters you need to replicate OR, it would be better to be able to just reference the duplicate filters once and us the 'OR' statement for the two fields that differ.
