is it possible to reduce the RAM usage of specific component of SP search service

i know that it is possibility to use this powershell command 
Set-SPEnterpriseSearchService -PerformanceLevel Reduced
and then change the value of memory limit in config file for noderunner

but there is only one config file where the limit can be set. i want for example the crawl component of noderunner memory limit to be set to 1500MB and for query processing component the limit to be set to 1000MB
is this somehow possible?

thank you
