Spacing notes, rests and grouped eighth notes, sixteenth notes, etc in a measure.

I recently enter a composition into a competition. The conductor to told me that the spacing of the notes and rests were making it difficult for the musicians to distinguish the beats in each measure. He told me that Sibelius and Finale both arrange the notes in each measure to be easily readable automatically. I am trying to find out if there is a way for MuseScore to do this automatically. I have attached an example of what I'm talking about. Notice in Screenshot1 the B flat clarinet part how there is not very much space between the eighth note (2nd half of the 1st beat) and the sixteen notes (which are the 1st half of the 2nd beat).
Notice in Screenshot2 how there is no space between the grouped sixteenth notes and the quarter rests.
Also in some cases I have eighth note rests or sixteenth note rests that are too far away from the remainder of the beat. and in that case the notes of the beat need to be tighter.
I have plenty more examples but this should be enough to support my question. I don't know if this is an issue or if I just don't know how to accomplish creating more space between beats.
