I use Dynamic Block and insert attribute field for value - placeholder - name. here is a print screen - http://joxi.ru/l2ZYpRXU88VExm

If i attache the file from a reference in another file, this bloc shows  the block name and file name in attribute value.

Maybe this will get you started on what you want to do.

If you go to the properties on the text and notice in the CONTENTS. This is getting the name of the drawing file. 

$(substr,$(getvar,dwgname),1,$(-,$(strlen,$(getvar,dwgname)) ,0))

The 1 and 0 are the numbers you want to adjust depending on how you want the string to appear. If you change the 1 to a 2 you'll remove the first character in the string and 3 will remove the first two characters in the string.

Also, if you change the 0 to 4 you'll remove the last four characters in the string.
