[Feature request] Add "find" in export

Export configuration with filter “find where …”. I assume this is something easy to add in current routeros but also very useful for customers. In many cases, we need to export certain configuration by filtering. For example Sync common configuration between routers automatically without external software. Distribute common IP address list from main router to other branch routers. And so on… export filter will help thousands of people and thousands of networks to automate much easy, straight forward and makes routeros scripting capability more powerful.
