 Since $X$ is compact, we may assume without loss of generality that the cover $\cU$ is finite.

 After subdividing $P$, we may assume that there exists $g\in \Homeo(X)$

 The sense of ``small" we mean will be explained below.
 It depends only on $\cU$ and the choice of $U_\alpha^i$'s.

+We may assume, inductively, that the restriction of $f$ to $\bd P$ is adapted to $\cU^N$.
+So $\bd P = \sum Q_\beta$, and the support of $f$ restricted to $Q_\beta$ is $V_\beta^N$, the union of $k-1$ of

 to choose a homotopy $h:P\times [0,N] \to \Homeo(X)$ with the following properties:
