I'm afraid I'm also not using Modbuddy...
in the modinfo it would be like that
Code:
<FrontEndActions>
<UpdateDatabase>
<File>MyData.xml</File>
</UpdateDatabase>
</FrontEndActions>
and in your xml file something like that (example from the Vietnam DLC)
Code:
<MapStartPositions>
<Row Map="../../Assets/Maps/EarthMaps/TSLEarthStandard.Civ6Map" Plot="3677" Type="LEADER" Value="LEADER_KUBLAI_KHAN_CHINA"/>
<Row Map="{4873eb62-8ccc-4574-b784-dda455e74e68}Maps/EarthMaps/TSLEarthStandard_XP2.Civ6Map" Plot="3677" Type="LEADER" Value="LEADER_KUBLAI_KHAN_CHINA"/>
<Row Map="../../Assets/Maps/EarthMaps/TSLEarthStandard.Civ6Map" Plot="3088" Type="LEADER" Value="LEADER_LADY_TRIEU"/>
