Manually add 1% to analog output post processing via an input

Please see my attached image

In capture 1, Input 10 toggles random/manual analog outputs and all works fine.

I am trying to add 1% offset manually via input 12 to the final analog value no matter what is happening prior in the program.  I suspect I can use B151 Analog MUX or B149 and a mathematical equation but I can't see the solution and the potential relationships.

As always, any help is always appreciated

What is 1% of what to you?

Good point, I should have been more clear.  Analog output is 0 to 1000 so let's say when I trigger a push button physical input,  I want to add 10 to whatever the current value happens to be.

I think this is essentially adding an offset of 10 but I can't see where the relationship is

And how long will the 10 units be added?

Constant?

Or just as long as I12 is pressed?

 Again, good point.  Let's say constant and another 10 will be added if I12 is pressed again.  So each time I12 is pressed, 10 will be added to whatever AQ1 happens to be and, if I12 is pressed again, another 10 is added and so on.

So added to the output value of B149?

 Yes, I think so.

So added to the output value of B149?

 Yes, I think so. 

 I came up with this but it only goes up by 9, not 10.  This increase of 9 rather than 10 is not a concern and it works.  Curious how I would get an increase of 10 though
