[Therion] Aven colour by loop error

Following on from this thread <https://www.mail-archive.com/therion@speleo.sk/msg04871.html> 2.5 yrs ago where I was asking about Therion support of Aven features. Therion files exported to .3d format now display 'colour by' depth, survey date, gradient and leg length when viewed with Aven. But not colour by loop error. Is 'colour by loop error' something that could readily be added to the Therion export? Bruce
