Exponent notation

[migueldvb]

I would like to use numbers in siunitx where the main number and uncertainty have exponents like:

\num{1.1e-2\pm0.1e-2}

However this gives a "Misplaced sign token error" and I have to first find a common exponent for both quantities and write the exponent in the end:

\num{1.1\pm0.1e-2}

This gives the expected output of 1.1(1) x 10^{-2}.

I think that it would be easier to make the syntax in the first example, or perhaps something with different exponents like \num{1.1e-2\pm1e-3}, equivalent to \num{1.1\pm0.1e-2}?
