vector - pair uniform initialization

i have a collection defined as -

using Parameters = std::vector<int>;
using Group = std::pair<std::string, Parameters>;
std::vector<Group> inputs;

intention is to use statement like -

inputs.push_back(group0 /*What goes in here ?*/);
inputs.push_back(group1 /*What goes in here ?*/);

How can i initialize group0 and group1 using initializer list ? A code like inputs.push_back(std::make_pair("group0", {1, 2, 3, 4})) doesn't seem to work.
