Does package support storing info in global attributes?

[DanSchnell]

I noted the following in the link to loom file format specs:

**Global attributes¶
There MUST be an HDF5 group /attrs containing global attributes.

There MUST be a HDF5 dataset /attrs/LOOM_SPEC_VERSION with the value 3.0.0.

Global attributes apply semantically to the whole file, not any specific part of it. Such attributes are stored in the HDF5 group /attrs and can be any valid scalar or multidimensional datatype.

As of Loom file format v3.0.0, only one global attribute is mandatory: the LOOM_SPEC_VERSION attribute, which is a string value giving the loom file spec version that was followed in creating the file. See top of this document for the current version of the spec.**

Is there a way I can use loomR (or other R codes) to populate /attrs with info such as genome & transcriptome references using loomR?
