Defined suggested values for ENTITY_LINK attribute (Like searching)

Hi,

Is there a way, how to use wildcard characters or like searching in the business rule „Define suggested values based on filter“ for ENTITY_LINK attributes?

For example when there would be 4 names: Chris, Christine, John, Paul and we would like to select only names which contains „Chris“ (Chris, Christine). Our customer has a big amount of data for some of their Offering User options ENTITY_LINK attributes and they can filter it out only this way.

Thank you very much for any advice.
