Hi Peter,

sounds nice, would be a great feature. For everyone else how is not using
a custom server: if you are lucky you can use the trim tool on tabs to
solve your problem.

If you want to add text to the beginning or end of a column:
- Use add column and add the text as a new column
- Then use cut to get everything in the right order
- finally join the new column with the column you want to add the text to
I hope you get what I mean and is helpful to someone

Using these tricks I have created a work flow that serves as my custom sam
to gff converter. Of course its terribly inefficient, but it gets the job
