If the aspects are related to same issue then you can club, otherwise the energy will get divided.
I feel rather than doing VOB on all affirmations together, do VOB on organs for health issues.
VOB can be done on multiple organs back to back or as divided .
With multiple aspects, you can design your healing like some in water, some as VOB , some as direct request, some on paper.
In every persons life there are actually few priorities which can be focussed first, the remaining can be taken care just with VK charged water.
You can always request VK GOLDEN SUNRISE GUIDE ME MY PRIORITIES and PLACE THEM IN FRONT OF ME.
Sometimes we feel that we want everything NOW , but DIVINE has ways to give us all at the right time.
But if you feel VK has guided you that way, you can do it.
