[ENH] Option to mark specific parts of a template to distinct unique configurations

Is there an existing issue for this?

New feature

Currently anything that matches the form of the below template will all be handled with the same identity.

sub-{participant}[_ses-{session}]_task-{task}[_acq-{acq}][_ce-{ce}][_dir-{dir}][_rec-{rec}][_run-{run_index}][_echo-{echo}]_bold.nii.gz (task_image)

If there was an option to use a special character to mark a specific placeholder to store unique configurations that could be very useful. ie.

sub-{participant}[_ses-{session}]_task-{*task}[_acq-{acq}][_ce-{ce}][_dir-{dir}][_rec-{rec}][_run-{run_index}][_echo-{echo}]_bold.nii.gz (task_image)

The '*' marked at task would then allow the program to know that different tasks should be considered as a different item.
Currently a user would have to manually write out different templates in the tree file. i.e.

sub-{participant}[_ses-{session}]_task-{task}[_acq-{acq}][_ce-{ce}][_dir-{dir}][_rec-{rec}][_run-{run_index}][_echo-{echo}]_space-MNI[_desc-{desc}]_bold.nii.gz (task_image_MNI)
sub-{participant}[_ses-{session}]_task-{task}[_acq-{acq}][_ce-{ce}][_dir-{dir}][_rec-{rec}][_run-{run_index}][_echo-{echo}]_space-T1w[_desc-{desc}]_bold.nii.gz (task_image_T1w)

to distinct between MNI and T1w files.

This may not be super important at this time because its pretty easy to just copy and paste to make these unique configurations. Where this fails is if there are many different variations for one type of value.

Another weird thing is if you leave the more general template in the file_tree its possible for the thing you are trying to be specific toward to be misclassified. If you order the more general one to be beneath the specific version it seems to work fine, but thats definitely not user friendly. This is an issue that I think is resolvable anyway.
