I have added the ability to upload a file when adding a Download to the Query and Template store (Downloads).
To upload a file simple click the add download option, then type a name for the file and a description and click the upload file and select the file you want to upload, the small window should then say 'click here' this will insert the location and name of your newly uploaded file to the url field.
Finally click the save button to save it.
Any files which are Family Historian customising files can be uploaded.
