Dynamic dropdown select All from dropdown list only

I currently have a dropdown that is working properly but I want to add an All selection and make it default. The problem I am running into is either it will select all items in the inputlookup or it will return nothing. XML for working dropdown:

Project NamePROJ_NAMEPROJ_NAME| inputlookup_assets.csv | search "ProjectCode"=99* | fillnull value="No Project Name" PROJ_NAME | dedup ProjectCode | table PROJ_NAME-15mnow

This will create a dropdown like: Project ABC Project DEF Project XYZ And yes there are spaces in the output. I have tried something like this:

Project NamePROJ_NAMEPROJ_NAME| inputlookup_assets.csv | search "ProjectCode"=99* | fillnull value="No Project Name" PROJ_NAME | dedup ProjectCode | table PROJ_NAME-15mnowAll Projects**

But this returns ALL ProjectCodes and is not limiting it to 99* I also tried the following:

Project NamePROJ_NAMEPROJ_NAME| inputlookup_assets.csv | search "ProjectCode"=99* | fillnull value="No Project Name" PROJ_NAME | dedup ProjectCode | table PROJ_NAME-15mnowAll Projects[| inputlookup_assets.csv | search "ProjectCode"=99* | fillnull value="No Project Name" PROJ_NAME | dedup ProjectCode | table PROJ_NAME]PROJ_NAME="$value$"

This just returns nothing. Any help would be greatly appreciated.
