I would like to put a ref to one of the slides created with AtBeginSection, is that possible?



In more detail, I abuse



setbeamertemplatebackground canvas%
hspace.8textwidthincludegraphics[width=.2paperwidth,height=paperheight]./symmetry_breaking.pdf


subsection[shorttitle]long title with texorpdfstring$x^2$x2 labelsym


beamertemplateshadingbackgroundblue!01!whitewhite


to manipulate the background image on one AtBeginSubsection slide. And as you see I try to put a label there, such that on the very last slide I can ask "Who spotted the mistake on slide refsym?"



Can I put labels on these auto generated slides?



(Alternatively, I'm also open to a workaround putting the label on the next slide and then do arithmetics to figure out the slide number before.)



EDIT: at the moment my file looks (cut down to a MWE) like this:



documentclassbeamer
usepackagegraphicx

beginframe<beamer>
tableofcontents[currentsection,currentsubsection]

subsection1234

beginframe

beginitemize
item headache ahead
item<2-> Bonus points for those who spotted the mistake on slide~refsym
enditemize
endframe

enddocument


and it includes this image just an image (suffered in the conversion, but for what it's worth here, can be any image).



And I build with



rm -f pseyfert.aux pseyfert.toc pseyfert.snm
xelatex pseyfert.tex
xelatex pseyfert.tex
xelatex pseyfert.tex


The last slide looks like this enter image description here and should say "Bonus points for those who spotted the mistake on slide 3"

    Add a command with which you can choose to label the next subsection added with AtBeginSubsection to your code:
