Convert image attachment to PDF within Evernote (NOT exporting)

[ChicagoBeck 0]

I am trying to convert image attachments (png or jpg usually) to PDF within a note -- NOT exporting the note to a new file location as then I'd have to reimport the new PDF to Evernote and delete the original note.  I'm on a PC.  I know I can print the note and select Adobe PDF, but then I am required to save the file as something else, and I would have to reimport the new PDF into Evernote, then delete the original note.  There must be a simpler way.  I do have Adobe Acrobat XI Pro, in case that could be useful somehow. 

Here is a scenario so you can see what I am trying to accomplish:  My boss will take a picture or save a screenshot of a bill for me to pay.  He then texts the image to me.  I open the image on my phone and export it to Evernote, then open Evernote on my PC.  There are stamps within Adobe that I use to mark "Paid" along with the date, so I need to convert the image to a PDF so that I can do so.  

I just can't find a way to do this while saving the original file location so that I don't have to export to PDF, then reimport into Evernote. 

Any suggestions?  Thank you.

I have found a workaround by "sharing" the picture on my iPhone to "Save PDF to iBooks," then from there I "share" again, only this time I select email to my EN email address.  Then the picture is imported to EN originally as a PDF.  This is a bit long.  There still seems like there must be a way to convert an image attachment to a PDF WITHIN the EN note. Thanks.

Evernote doesn't have an attachment-format-conversion feature.
Personally, I'd export the attachment; use my conversion software; then drag the attachment into the same note.  
On my Mac, it isn't even an export; I right click, open in Preview; export to pdf

On my Mac, I have this option to convert a note to PDF but it still means a new note, and you have to delete the original note
