Multiple URLs in Mendeley

Question

Motivation

It is often the case that I save multiple urls for the same Mendeley reference, for example, link to a paper and another link to its video, so that I can easily find just by clicking on it from Mendeley. Also I want that I have all these links in the draft/presentation so that the readers can do the same.

But I couldn't figure out a nice automated way to do it. Of course, one way is to change url to note but there are various problems:

1. I don't find note in the available fields for most commonly used document types (conference proceedings, journal article and generic) in Mendeley.
2. I cannot make use of the simple functionality of click to open in Mendeley
3. It is indeed a lot of manual effort if I try to change each url to note

Hence, the solutions proposed in How to use multiple URLs for one bibtex reference? are not useful. For instance, doing the following does not help. Any automated way of handling this would be great.

  abstract =    "An adaptive mesh projection method for the
         time-dependent incompressible Euler equations is
         presented. The domain is spatially discretised using
         quad/octrees and a multilevel Poisson solver is used to
         obtain the pressure. Complex solid boundaries are
         represented using a volume-of-fluid approach.
         Second-order convergence in space and time is
         demonstrated on regular, statically and dynamically
         refined grids. The quad/octree discretisation proves to
         be very flexible and allows accurate and efficient
         tracking of flow features. The source code of the
         method implementation is freely available.",
