SUGGESTION: export with preset - custom subfolder name

Question

i've got various export presets set up in LR; for exporting to flickr, exporting for forums, exporting for print etc.  however, one thing that bugs me is that –at least as far as i can see– the export preset requires me to 'hardwire in' the name of the folder [or subfolder] that that preset exports to.
ideally i'd like either:
* to have the ability to create a preset where LR would throw up an OS standard open/save dialogue asking me where to save the exported image/s to
or even better:
* be able to dynamically create subfolder names at export time.  for example.  my "flickr" preset exports to a folder called "flickr formatted".  at present every image i export using this preset just ends up in that folder and i then have to manually sort them into subfolders.  in the preset setup dialogue, i can tick "put in subfolder" and then fill in a name, but that's a bit pointless, as it's just as 'hardwired' as the main folder name.
it would be nice if i could tick "put in subfolder" and then enter a PHP style dynamic subfolder name, such as "%Y-%M-%-%D" to create dynamically named subfolders and sort my exports by date.
how about it adobe?

Answer 1

yes. i've seen that option.  but wouldn't that require you to select the folder each time you exported? that would soon become tiresome.
what i want is an option to have the preset dynamically generate the folder name [probably based somehow on current date]. then, each day's export session would be placed in its own subfolder, without having to:
A: define the export folder each time
or
B: manually sort photos into subfolders afterwards
