Some time ago it was possible to do specific searches to fill the 81 matrix of different kinds only

Question

Some time ago it was possible to search for D/T combinations to fill e.g. the matrix for one type of caches (e.g. Multi-Matrix). If I search for missing D/T combinations now and set a filter to "Multi Cache", it shows only caches which fills the next loop of the total matrix.

I would like to search for caches which fill my 81 Multi- or Letterbox- matrix specifically. The search tool only provides caches which will fill the total matrix to the next loop.

Previously, you probably used the "D/T Type/Size" filter to achieve this.

Now, you can use the "pre" and "post" filters to achieve this. Specifically, you will want to add a "pre-Type/Size" filter for the type of interest (to tell the system that you are pursuing a D/T grid of some type), and then use the "post" filters to narrow down the suggestions to geocaches near you. Here is a direct link:

This change was released some weeks ago to facilitate better flexibility of the Map Matrix tool. Filters can separately be applied to "pre" and "post", so for example you can apply a "pre-Location" filter to fill a D/T grid in a particular country or region or apply a "post-Location" filter to fill a D/T grid, but limit suggestions to those in a particular country or region.
