title: QGIS Save results of object query from WMS layers to attribute table of another layer
body: <p>I am a newbie in QGIS and would like to solve the following problem:</p>
  <p>I have loaded drill points as a point layer (attribute table with name and coordinates) in QGIS. Beside that I have added some WMS services, whose attributes I want to know at a certain drill point. This works so far by manually selecting the desired WMS layer and starting the object query with a mouse click at a specific drilling point. However, with many drill points and many WMS layers, this becomes tedious at some point.</p>
  <p>Is there a way to add the results of these point/coordinate specific (X1/X2) object queries of multiple WMS layers to the attribute table of my drilling points? I want my attribute table to look like this:</p>
  <p>Drilling point 1, X1, Y1, object query WMS layer geology (X1/Y1), object query WMS layer flood plain b. (x1/y1)</p>
  <p>Drilling point 1, X2, Y2, object query WMS layer geology (X2/Y2), object query WMS layer flood area b. (x2/y2)</p>
  <p>...</p>
  <p>I thought, if necessary, something like this is possible via the field computer, but I haven't found a way so far.</p>
