Server Connect: Dynamic input parameters

Hi guys,

is it possible to dynamically change the sources used at the input parameters in the server connect options?
I have a table with a filter for each column. What I want to do is to change the source of the filter as I change the focus on a certain text input. In other words, normally, the table is filtered with the standard filter, but as soon as I click on a certain text input, the table should be filtered by another text input.
I hope you understand what I mean. For days now I try to figure this one out!

Thanks in advance!
