Yes, by using a block container with an initial size but allowing the 
size to grow.

The diagrams came through quite well ... well done.

Block containers can grow if you don't set the maximum component of 
its block-progression-dimension.

The following works in Antenna House, but I see that it does not work 
in XEP ... I had anticipated it would:

  <block-container block-progression-dimension.minimum="3cm">
    <block>Test1</block>
  </block-container>
  <block>Test 1 end</block>
  <block-container block-progression-dimension.minimum="3cm">
    <block>Test2</block>
    <block>Test2</block>
    <block>Test2</block>
    <block>Test2</block>
    <block>Test2</block>
    <block>Test2</block>
    <block>Test2</block>
    <block>Test2</block>
    <block>Test2</block>
    <block>Test2</block>
  </block-container>
  <block>Test 2 end</block>

In ASCII art the above gives me:


Test1



Test 1 end
Test2
Test2
Test2
Test2
Test2
Test2
Test2
Test2
Test2
Test2
Test2
Test2
Test2
Test2
Test 2 end


I'm not sure what changes would be needed for XEP.

I hope this helps.
