Make upgrading of walls with elixirs available at level 1 or...

Why not make it such that walls can be upgraded with Gold/ Elixir even when during level 1?
OR
Why not make it such that you can select an entire stretch of 10 walls and the system will automatically upgrade the maximum number of walls you can upgrade?

I mean when we have level 6 walls it costs 200k to upgrade to level 7. In order to upgrade to level 7 walls our Town Hall must be at level 7. Which makes our gold and elixir storage to have 2mil at max. So we can upgrade a total of 10 walls what if we have 16 walls in a row? We still have to manually upgrade 6 walls then upgrade 10 walls with 2mil elixirs. To make things worse, its rather hard to get 2mil elixirs or gold since people keep raiding your base every now and then. Which makes the "Upgrade using elixir" function to be "as good as useless" to a certain extend.
