Suppose you have a homogeneous ideal $I$ inside the algebra $\mathbb{C}[x_1,...,x_d]$  of complex polynomials in $d$-variables. Can one find a basis for $I$, say $\{f_1,...,f_k]}$, such that every $h \in I$ can be written as 

$$h = a_1 f_1 + ... + a_k f_k $$

where the coefficients appearing in each summand $a_i f_i$ are not much bigger then the coefficients appearing in $h$?
More specifically, given that $\{f_1,...,f_k}$ is a Groebner basis for $I$, can one modify the standard division algorithm so that one gets 
$h = a_1 f_1 + ... + a_k f_k$
with controlled terms?

I will share that I found this possible in some special cases, for example when $d=2$ or when $I$ is generated by monomials, and I am now interested in the general question.

Note: My question begins *after* a basis has been found, I am *not* concerned here with the terrible complexity of actually computing a Groebner basis.
