Hi Jane, I used the Direct Import. I would have to see if a Gedcom file contains this particular field. Thank you also for pointing out the plugin, I will check it out. Actually, the values in my reference fields are references to the actual scan of the respective source (their file names), this is why this is so important (I keep the image/document scans separate from my genealogy program).
However, I have played around with this a bit in the meantime and found at least a work-around using TMG Utility (donorware, separate from TMG, available at
https://www.johncardinal.com/tmgutil/index.htm). It moves the content of the Citation Reference field to the Citation Memo field which is indeed copied over to FH in the conversion process. I am posting this work-around here in case someone has the same problem as I do:
In TMG Utility, open your TMG database (I strongly recommend working with a copy at first to make sure the results are what you want).
Go to Citations > Change Citation Parts.
For the 'Filters' box, select 'If Reference' 'is not empty'.
For the "Actions" box, select 'Change Memo' 'append', then enter [CREF] into the blank field.
If you are absolutely certain that you never entered any content into the Citation Memo field in your project, you can also set the following rule:
Go to Citations > Change Citation Parts.
For the 'Filters' box, select 'If Reference' 'is not empty'.
For the "Actions" box, select 'Change Memo' 'copy', then select 'Reference' from the drop-down list. Note though that this option will overwrite any content already present in the Citation Memo field.
Then click OK, and for extra-safety, select the "Log Only" option which will not change your actual data but only do a test run to see if this is yields the desired results. To actually implement these rules for your TMG project, uncheck "Log Only".
Hope this helps someone, and thank you very much, Jane, for responding to my question!
