I am using a trigger to update a file upload field with a specified document template. However, the name of the file in this field is automatically generated as something like "tmp_1232354534.htm".
How can I specify what I would like the name of this file to be when the template is updated to the fiel upload field via the trigger? See the attached screenshot.
Thanks 
What type of trigger you're using?
I'm using a "Create Template Document" trigger to update the file upload field with the document template
OK, will fix that.
Is there a way to name the file with tokens from the respective object?
From next release original file name will be used.
